JEWEL SETTER.

Application fi led June 21,

To all whom it may concern:

Be it known that I, HENRY F. BRATZ, a citizen of the United States, residing at Eau Claire, in the county of Eau Claire and State of lVisconsin, have invented new and useful Improvements in Jewel Setters, of which the following is a specification.

This invention relates to tools for use by watch makers and has for its object the provision of a novel device for use in setting jewel bearings.

An important object is the provision of a tool of this character which includes a rotary disk upon which the jewel is held, this disk being normally held against rotation so that displacement of the parts will be prevented whi'le the work is being done.

Another object is the provision of a device of this character in which the disk is formed with openings of diiferent shapes and sizes depending upon the nature and dimensions of the jewel to be set.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture, a great time and labor saver in use, durable in service and a general improvement in the art.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the device,

Figure 2 is an elevation at right angles to Figure 1,

Figure 3 is a cross section showing the device in use,

Figure 4.- is a view of the head on a larger scale showing in dotted lines a wheel memher mounted thereon.

Referring more particularly to the drawings I have shown my tool as comprising a handle 10 to which is secured and from which extends an elongated shank 11 upon the free end of which is rotatably mounted a disk 12 which may have its periphery toothed if preferred. This disk is formed in its periphery with a plurality of openings 13 of different sizes and shapes for holding ewels to be set, and the disk is further 1922. Serial No. 570,003.

formed with openings 13 which are of different length and width.

For preventing casual rotation of the disk, I provide an elongated spring member 14: which extends along one side of the shank and which has-one end secured as for instance as by being inserted with the shank into the handle 10. The other end of this spring is formed as an arcuate bearing shoe 15 which en ages the periphery of the disk 12. Intermediate its ends the spring carries a projection 16 which is in the nature of a lug and which extends across and beyond the shank in position to be engaged by the operators thumb for pressing the spring out of engagement with the disk 12.

In the use of the device it will be seen that the roller jewel is inserted within the proper opening so that it will be held firmly and straight. All that is then necessary is to set the balance on the jewel and cement it. This tool therefore saves time and labor and operates to set the jewel perfectly true. It is believed that from the drawing and the above description the operation and advantages will be clear to one versed in the art without further explanation.

While I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, con-. struction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention I claim:

1.. A tool of the character described com prising an elongated shank provided at one end with a handle, a head member pivoted upon the other end of the shank and formed as a disk provided at one side with an elongated tongue said disk being formed with a plurality of radial openings of different sizes adapted selectively to receive the arbor of a gear or balance wheel. the disk being provided at its periphery with recesses opposite the outer ends of said openlngs.

2. A tool of the character described comprising an elongated shank provided at one end with a handle, a head member pivoted upon the other end of the shank and formed as a disk provided at one side, with an elongated tongue, said disk being formed with a plurality of radial openings of different sizes adapted selectively to receive the v 5 arbor of a gear or balance Wheel, the disk being provided at its periphery With recesses opposite the outer ends of said openings, and an elongated spring tapered throughout its length and having its larger end secured Within the handle and its smaller end formed With an arcuate shoe frictionally engaging the disk the intermediate portion of the spring carrying a finger piece to receive pressure for moving the spring out of engagement with the disk.
